É referente aos registros de patente, será que o meu modelo 30353, é de algum ano próximo a 1904?
3. Obtained Patents
A patent office was founded in Switzerland not before 1888. Hence Roskopf was not able to patent his inventions in Switzerland. At least he patented his inventions in France, Belgium and the USA, then the world's major watch centers. That’s why Roskopfs watches were copied in Switzerland frequently.
French patent # 54528, on 18 June1862 Georges-Frederic Roskopf patented his crown winding system
Belgium Patent # 21988, 3 Aug 1867
USA Patent #75463 10. March 1868 for an exchangeable escapement unit for watches (this patent says explicitly that the escapement may be adapted for use with a cylinder or lever as well as a pin pallet).
French patent # 80611, 25 March 1868 Georges-Frederic Roskopf - for a changeable escapement unit for watches. Here the watch was called: "Montre de proletaire" meaning "laborers watch"
And finally the Swiss patents after Switzerland established a patent office in 1888:
